United States Patent GOLF CLUB WEIGHTING MEANS James V. T. East,Chicago, Ill., assignor to Fawick Flexi-Grip Company, a corporation ofOhio Application March 8, 1954, Serial No. 414,607

3 Claims. (Cl. 273-81) This invention relates to golf clubs and has todo with means for changing the weight of the structure in the upper endportion of the club to give the club the desired balance, or position ofthe center of gravity.

My chief objects are to provide an assembly comprising a weightingmember easily mounted in relation to the rest of thestructure,,providing an ornamental appearance, having durability andpermanence of its positioning, and adapted to be readily modified toprovide one or another of several increments of weight in being mountedin the club.

The single figure of the accompanying drawing is an elevation of anupper portion of a golf club embodying my invention in its preferredform.

The club, with the usual head, not shown, comprises a tubular steelshaft 10, upon which is mounted, and preferably adhered, a rubber grip11 having an end wall 12 centrally formed with a hole of relativelylarge diameter for a distance inward from the outer face of the end walland then stepped down to a smaller diameter for the rest of the distanceinward through the end Wall, the end wall thus being formed with aninternal flange defining the small-diameter part of the hole.

The said flange, preferably under slight strain, tits in across-sectionally rectangular, annular groove formed in a weightingmember 13, of metal, plaster or other suitable material, the anchoringhead of the weighting member thus being of waisted form. The portion ofthe weighting member outward from said groove snugly fits in and fillsthe large diameter part of the hole in the end wall of the grip, withits outer face a smooth continuation of the curved contour of the outerface of the grip.

Inwardly from the mentioned groove the Weighting member 13, of generallycylindrical form, is formed with a series of spaced apart break-offannular grooves 14, 15, 15, preferably of triangular cross-sectionalshape as shown, and the innermost, terminal one of the sections definedby the grooves is similarly tapered at its inner end for easy insertionof the weighting member through the hole in the end wall of the grip.

2,782,035 Patented Feb. 19, 1957 When a lighter weighting member isdesired it is obtained by breaking off and discarding one or more of thesections, according to the weight desired, and as the break will alwaysoccur at the bottom of the chosen groove 15 or 14 the remaining part ofthe weighting member, because of the shape of the break-off groove, willhave a tapered inner end for easy insertion in the grip.

Because of the width and depth of the rectangular groove in the 'headportion of the weighting member, and the corresponding size and shape ofthe rubber flange occupying it, the weighting member, buttoned in thehole in the end wall of the grip, is securely and accurately held inplace even when, as shown, it contacts only the rubber of the grip.

The assembly as described provides the advantages that are set out inthe above statement of objects and is subject to modification withoutdeparture from the scope of the invention as defined in the appendedclaims.

I claim? 1. A hand-grip weighting assembly comprising a hollow shaftformed with an open end, a rubber hand grip mounted thereon and having,as a closure for the said open end of the shaft, an outer end wallformed with a central hole through it, and a weighting member freelyprojecting from said end wall into the shaft and having an anchoringportion of waisted form buttoned into the said hole and held in positionwholly by the resilience of the wall of said hole, the said weightingmember thus being held out of contact with the inner face of the saidshaft.

2. An assembly as defined in claim 1 in which the part of the weightingmember inward from its waist portion is formed with at least onebreak-off groove spaced from the said Waist portion.

3. An assembly-as defined in claim '1 in which the part of the weightingmemberinward from its waist portion is formed with at least onebreak-oil groove of inwardly tapered cross-sectional shape spaced fromthe said waist portion.
